ZL50015
Enhanced 1 K Digital Switch with
Stratum 4E DPLL
Data Sheet
Features
• 1024 channel x 1024 channel non-blocking digital
Time Division Multiplex (TDM) switch at 4.096,
8.192 and 16.384 Mbps or using a combination of
ports running at 2.048, 4.096, 8.192 and
16.384 Mbps
• 16 serial TDM input, 16 serial TDM output
streams
• Integrated Digital Phase-Locked Loop (DPLL)
exceeds Telcordia GR-1244-CORE Stratum 4E
specifications
• Output clocks have less than 1 ns of jitter (except
for the 1.544 MHz output)
• DPLL provides holdover, freerun and jitter
attenuation features with four independent
reference source inputs
• Exceptional input clock cycle to cycle variation
tolerance (20 ns for all rates)
